rinsing of the front glass to remove dust, dirt or other deposits.Do not use ground water containing calcium carbonatecomponents when cleaning glass.

• Aggressive and abrasive cleansers or chemicals such as alkali chemicals including ammonia based solution should not be used on cleaning the module.

• Always keep the back surface of the panel free fromany foreign objects or structural elements which couldcome into contact with the panel, especially when thepanel is under mechanical load.

• Deposits of foreign material on the frame surface can be cleaned by using a wet sponge or cloth and dried in air or by using a clean chamois.

• Perform the wiring work by connecting the connector and wires to the stand away from the roof or ground.

• Do not use any kind of oil or lubricant on the module'sany parts, It can defect the PV Module.

It may result in a burn or injury.

• Do not disassemble the solar module.

• After installation or repair, check that the solar module are operating properly.

• In the event that the currently used solar module or parts have been replaced the newly replaced module and parts must have the same model name and parts as the previously installed solar module.

• Do not let anyone approach the solar module who haslittle knowledge of solar modules or on the measures totake when solar modules are damaged in order to avoidthe risk of injury or electrical shock.

• Secure all necessary permits and licenses to install the solar modules.

• Do not locate the solar module horizontally, as this maycause dirt or white efflorescence(glass deformation).

• Panels are not intended for use indoors or on moving vehicles of any kind.

•conditions of 1000W/m irradiance and 25°C (77°F) solar cell temperature. Colder temperatures may substantially increase voltage and power.

• Keep the solar module and system away from children at all times.

• Keep the module packed in the carton until the time of installation.

•site.

• Do not work alone. Please work as part of a team of two or more people.

• Safety harness use is strongly recommended for installation.

• Partial shadowing may substantially reduce panel and system output and may be the reason for the damage of solar module.

• Care must be taken to avoid low tilt angles which may cause dirt to buildup on the glass against the frame edge.

• Dirt build-up on the surface of the panel may cause active solar cells to be shaded and electrical performance to be impaired.

• Be careful not to damage the cable when using a tool such as a knife to remove the cable tie that fixes thejunction box cable.

06

ELECTRICAL INSTALLATIONCaution• Avoid all electrical hazards when installing, wiring,

operating and maintaining all panels.

• Do not connect panels that have different electrical

system.

• Match the polarities of cables and terminals when making the connections; failure to do so may result in damage to the panel.

• When reverse currents can exceed the value markedon the name plate, a properly rated and certifiedover-current device(fuse or circuit breaker) must be connected in series with each panel or string of panels.

• The rating of the over-current device shall not exceed the maximum series fuse rating marked on the name plate.

• The panel contains factory installed bypass diodes located inside the junction box.

• When installing the system, it is recommended to install a lightning rod to protect the system.

• The induced overvoltage by lightning can cause the system damage, you should design conductor loop connection as minimum as possible.

• The junction box should not be opened. Opening the junction box will void the warranty.

• Panels with a suspected electrical problem should be returned to LG Electronics for inspection and possible repair or replacement as per the warranty conditions provided by LG Electronics.

Electrical Connections• Shock hazard may occur near the solar modules

exposure. The module generates maximum output power when it faces the sun directly. The tilt angle of the modules should be selected to optimize seasonal and sunlight-based performance in the installation place.

• Module should not be mounted or stored in a way that the front/top glass faces downward in order to prevent water from entering the junction box, which could cause a safety hazard.

• Clearance between the solar module frames and structures such as roofs or ground is required to prevent wiring damage and to allow air to circulate behind the solar module. The recommended standoffheight is a minimum of 100mm.
